Abstract
The Putnam Street Bridge Replacement carries traffic across the Muskingum River in Marietta, Ohio. The low bid on the project was $11.4 million in the spring of 1998. The three-span structure is 69.85 ft. wide-box precast structure built in balanced-cantilever with a longitudinal closure strip between the boxes. The Contractor, Kokosing Construction Co., proposed a Value Engineering Cost Proposal (VECP) to make the structure a single cell, full width cast-in-place box girder based on constructability issues and economics of the design. Parsons, as the Construction Engineers for Kokosing, developed this concept as an alternative, which resulted in a shared savings of $500,000 between Washington County, Ohio and Kokosing.
